Long-term Performance of Fresh Autologous Pericardium for Mitral Valve Leaflet Repair
ConclusionsFAP is an excellent substrate for complex mitral valve leaflet patch repairs and can be used with the expectation of durable, long-term valve function, without evidence of late patch calcification, stiffness, or aneurysmal degeneration.
Injection drug use-related infective endocarditis hospitalizations have markedly increased over the past decade. Right-sided infective endocarditis is strongly associated with intravenous drug use, and 90% of right-sided endocarditis involves the tricuspid valve. There has been an increase in the need for surgical therapy for tricuspid valve endocarditis. In this issue of Operative Techniques, Brescia and associates discuss the indications for tricuspid valve surgery for endocarditis and provide detailed description of techniques for tricuspid valve leaflet repair and augmentation.
This study aimed to analyze the early and mid-term outcomes of aortic valve replacement with bovine pericardium in the treatment of aortic valve regurgitation.From January 2015 to March 2018, 36 patients (19 men; mean ± standard deviation [SD] age, 46.70 ± 16.60 years) underwent aortic valve replacement with bovine pericardium. The bovine pericardium was intraoperatively measured and shaped using an Ozaki template, according to the shape and size of the individual patient's aortic valve leaflets. Additional procedures were performed, including ventricular septal defect repair in 5 cases, mitral valve reconstr...
Intravenous drug use has increased substantially over the past decade, with heroin abuse more than doubling. Injection drug use-related infective endocarditis hospitalizations have similarly increased over the same period. Right-sided infective endocarditis is strongly associated with intravenous drug use, and 90% of right-sided endocarditis involves the tricuspid valve. During the period of the opioid epidemic, tricuspid-related endocarditis rates have increased, while the incidence of surgery for tricuspid endocarditis has increased as much as five-fold.
Abstract The human chondromodulin-1 (Chm-1, Chm-I, CNMD, or Lect1) gene encodes a 334 amino acid type II transmembrane glycoprotein protein with characteristics of a furin cleavage site and a putative glycosylation site. Chm-1 is expressed most predominantly in healthy and developing avascular cartilage, and healthy cardiac valves. Chm-1 plays a vital role during endochondral ossification by the regulation of angiogenesis. The anti-angiogenic and chondrogenic properties of Chm-1 are attributed to its role in tissue development, homeostasis, repair and regeneration, and disease prevention. Chm-1 promotes chondrocyt...
In conclusion, we show here that sEVs are responsible for mediating paracrine senescence and speculate that they could be involved in inducing bystander senescence during therapy-induced senescence or aging. In fact, when compared to soluble factors, sEVs have different biophysical and biochemical properties as they have a longer lifespan than do soluble factors and they are more resistant to protease degradation. The idea that blocking sEV secretion could be a potential therapeutic approach to alleviate senescence "spreading" during chemotherapy-induced senescence or in aging tissues presents itself as a very at...

ConclusionsAlthough it is technically demanding, surgery for invasive IE involving IVF, which provides the only chance for cure, can be performed with reasonable clinical outcomes. In cases of IE invading the IVF and limited to the anterior mitral valve leaflet, a hemi-Commando procedure that includes mitral valve repair has improved early outcomes.
AbstractBackgroundContemporary data on mitral valve (MV) surgery in patients with infective endocarditis (IE) are limited.MethodsThe National Inpatient Sample was queried to identify patients with IE who underwent MV surgery between 2003 and 2016. We assessed (a) temporal trends in the incidence of MV surgery for IE, (b) morbidity, mortality, and cost of MV repair vs replacement, and (c) predictors of in ‐hospital mortality.ResultsThe proportion of MV operations involving patients with IE increased from 5.4% in 2003 to 7.3%, and the proportion of MV repair among those undergoing surgery for IE increased from 15.2% to 25.0% (Ptrend
